Wirsbo hePEX™ was the first and is the most widely used PEX-a tubing for radiant heating and cooling systems in North America. For more than 35 years, professionals have relied on our product for the consistent, superior performance it provides.

Benefits of PEX-a

Wirsbo hePEX™ is Engel-method crosslinked polyethylene (PEX-a) tubing with an oxygen barrier that prevents corrosion of ferrous components in a closed-loop radiant hydronic system. The tubing features the highest degree of crosslinking for the greatest durability and flexibility, and also offers the tightest bend radius (six times the tubing diameter) to help avoid kinks. However, in the unlikely event of a kink, PEX-a tubing is the only PEX tubing that can be easily repaired with a shot of heat from a heat gun without compromising the tubing’s integrity.
